July 29 (Reuters) – Microsoft topped Wall Street estimates for quarterly cloud revenue growth on Wednesday, a sign its massive spending on AI infrastructure was paying off as capacity constraints ease and more businesses adopt the technology.
Revenue at the company’s Azure cloud-computing business rose 43% in its fiscal fourth quarter, compared with analysts’ consensus estimate of 39.98%, according to Visible Alpha.
Shares of Redmond, Washington-based Microsoft were up about 3% in extended trading.
“This year, Azure revenue surpassed $100 billion for the first time, and Microsoft 365 Copilot reached over 30 million paid seats, reflecting the confidence customers are placing in us to power their AI transformation,” CEO Satya Nadella said.
The strong growth could ease concerns about the company’s surging data center outlays and fears that AI tools could displace its long-reliable productivity software business.
It follows Google Cloud’s blockbuster quarter, with the rival posting an 82% surge in cloud revenue last week, far ahead of market expectations.
SOLID PERFORMANCE
Microsoft reported contracted backlog of $678 billion in its cloud business at the end of the quarter, up from $627 billion in the prior quarter. It said all the sequential gains were driven by commitments from companies outside the leading U.S. AI model makers.
Its M365 Copilot paid seats totaled more than 30 million, compared with 20 million reported last quarter. Analysts on average were expecting 26.9 million Copilot seats, according to Reuters calculations based on estimates from Citi, Morgan Stanley, BNP Paribas and Wells Fargo.
Microsoft has forecast spending $190 billion this calendar year, part of the more than $700 billion in unprecedented Big Tech outlays that have strained the companies’ cash flows and stoked fears of capacity overbuild.
Capital expenditures for the April-June quarter were $41 billion, up more than 70% from last year, and compared with market estimates of $42.37 billion. Microsoft reported $31.9 billion in capital spending in the prior three-month period.
Meanwhile, the company is cutting dependence on OpenAI’s technology by adding Anthropic’s models into its offerings and developing in-house AI, while leaning on its deep business ties to boost adoption of the $30-a-month Copilot, including through deals such as the one with Accenture earlier this year.
The company is among the worst performers in the so-called “Magnificent Seven” group of mega-caps with an 18% drop so far this year, trailing cloud rivals such as Alphabet.
Microsoft has said its cloud growth is being held back by capacity constraints that it expects to persist at least through the end of 2026. That has forced the company to choose between powering its own AI services such as the Copilot 365 assistant and renting computing power to customers through Azure.
Still, some analysts say the concerns around Microsoft are overblown, noting that AI demand remains strong and it has made efforts to ease constraints through deals beyond its own data-center build-out, such as a recent tie-up with France’s Mistral.
Overall revenue for the quarter rose 18% to $90 billion, beating estimates. Its per-share profit, excluding the impact from investments in OpenAI, was $4.74, beating expectations of $4.24.
